Module 7 Unit 23 – Instrumentation and Control Drawings
Learning Objectives Describe the types of control diagrams. Identify symbols used on fluid power diagrams. Recognize supplementary information accompanying circuit diagrams. Read a graphic diagram. Interpret graphic diagrams for fluid control devices.
Graphic Diagram Components and piping are shown as schematic symbols
Pictorial Diagrams Components are shown in a pictorial form and piping shown as lines
Cutaway Diagrams Components are shown in a cutaway form Emphasizes the internal functions and connections
Instrumentation and Control Diagram Terminology Accumulator: Container in which fluid is stored under pressure as a source of fluid power Actuator: Device for converting fluid power energy into mechanical energy (i.e., motors and cylinders) Circuit: Complete path of flow in a fluid power system
Instrumentation and Control Diagram Terminology Component: Single hydraulic or pneumatic unit Control: Device used to regulate the function of a component Enclosure: Housing for components –Indicated by a phantom line rectangle in diagrams Fluid: A liquid or gas
Instrumentation and Control Diagram Terminology Port: End of a passage in a component Reservoir: Container for storage of liquid in a fluid power system not under pressure Restriction: Area in a line or passage with a reduced cross section that produces a pressure drop
Fluid Power Diagram Symbols In a diagram, lines can be solid or dashed and may include dots or arrows to assist the print reader with interpreting the circuit
Fluid Power Diagram Symbols In a diagram, there are various symbols for units such as motors, heaters, coolers, accumulators, etc.
Fluid Power Diagram Symbols In a diagram, there are various symbols for springs, switches, and other operating buttons
Fluid Power Diagram Symbols In a diagram, there are various symbols for valves and other flow-control devices
Pneumatic Diagram Example Refer to the sequence of operations on pages 403–405 of text for this circuit
